Is there some other preferred name for localhost? I was under the
impression that that name was required by some dusty RFC or other.
Assuming that you're speaking of the statistics collector's port, we do
not really want that to be "configurable" because there is no possible
reason for allowing it to bind to anything except the current host.
There would be a lot more potential for breakage than positive results
if we exposed a configuration knob for that.
I recall that we did debate relying on "localhost" versus hard-coding
"127.0.0.1", and rejected the latter because IPv6 might be preferred
on some systems.
